2014-05-14dfu: mmc: Provide support for eMMC boot partition accessLukasz Majewski
Before this patch it was only possible to access the default eMMC HW partition. By partition selection I mean the access to eMMC via the ext_csd[179] register programming. It sometimes happens that it is necessary to write to other partitions. This patch adds extra attribute to "raw" sub type of the dfu_alt_info environment variable (e.g. boot-mmc.bin raw 0x0 0x200 mmcpart 1;) It saves the original boot value and restores it after storing the file.

2014-05-05dfu: mmc: change offset base handlingMateusz Zalega
Previously offsets handled by dfu_fill_entity_mmc(), defined in boards' CONFIG_DFU_ALT were treated as hexadecimal regardless of their prefix, which sometimes led to confusion. This patch forces usage of explicit numerical base prefixes.

2014-05-05dfu: mmc: raw data write fixMateusz Zalega
When user attempted to perform a raw write using DFU (vide dfu_fill_entity_mmc) with MMC interface not initialized before, get_mmc_blk_size() reported invalid (zero) block size - it wasn't possible to write ie. a new u-boot image. This commit fixes that by initializing MMC device before use in dfu_fill_entity_mmc(). While fixing initialization sequence, I had to change about half of dfu_fill_entity_mmc's body, so I refactored it on the way to make it, IMHO, considerably more comprehensible. Being left as dead code, get_mmc_blk_size() was removed. Tested on Samsung Goni.

2014-03-23dfu: mmc: Replace calls to u-boot commands with native mmc APIŁukasz Majewski
For some time we have been using the run_command() with properly crafted string. Such approach turned to be unreliable and error prone. Switch to "native" mmc subsystem API would allow better type checking and shall improve speed. Also, it seems that this API is changing less often than u-boot commands. The approach similar to env operations on the eMMC has been reused. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>
2014-02-20dfu: mmc: fs: Fix format accepted by ext4write commandLukasz Majewski
The commit: "EXT4: Fix number base handling of "ext4write" command" SHA1: f7740f7712b8638f08b83a7e5d00bc1d6bb086a9 Cleaned up the ext4write command format. This commit shall be regarded as a follow up, since the DFU subsystem is using those commands for its normal operation. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>
2013-09-24dfu: unify mmc/nand read/write ops enumAfzal Mohammed
MMC and NAND independently defines same enumerators for read/write. Unify them by defining enum in dfu header. RAM support that is being added newly also can make use of it.

2013-07-03dfu:ext4:fix Fix ext4{read|write} command formattingŁukasz Majewski
In the following commit: "dfu: Support larger than memory transfers." SHA1: ea2453d56b8860dbd18a3c517531ffc8dcb5c839 The ext4{read|write} command formatting has been changed. It removed a write mandatory [sizebytes] parameter. It extents DFU_FS_EXT4 case at mmc_file_op to provide mandatory parameter for DFU write.

2013-04-10dfu: Support larger than memory transfers.Pantelis Antoniou
Previously we didn't support upload/download larger than available memory. This is pretty bad when you have to update your root filesystem for example. This patch removes that limitation (and the crashes when you transfered any file larger than 4MB) by making raw image writes be done in chunks and making file maximum size be configurable. The sequence number is a 16 bit counter; make sure we handle rollover correctly. This fixes the wrong transfers for large (> 256MB) images. Also utilize a variable to handle initialization, so that we don't rely on just the counter sent by the host.

2013-04-08dfu:ext4:fix: Change ext4write command order of parametersŁukasz Majewski
Following commit: "cmd_ext4: BREAK and correct ext4write parameter order" SHA1:0171d52c410cbaa9290b1b214e695697c835bfe5 introduced cleanup of ext4write semantics to be consistent with other filesystem's writing commands (e.g. fatwrite). This commit provides correct ext4write command generation at DFU eMMC code. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
